Sequoia jeholensis is the oldest recorded member of the genus Sequoia (along with Sequoia portlandica, but this name is a nomen dubium), known from the Jiufotang Formation (Lower Cretaceous) and the Jiulongshan Formation (Middle Jurassic) of China. [8]
Sequoia sempervirens (/ s ə ˈ k w ɔɪ. ə ˌ s ɛ m p ər ˈ v aɪ r ən z /) [3] is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200 ...
The extinct genus Austrosequoia, known from the Late Cretaceous-Oligocene of the Southern Hemisphere, including Australia and New Zealand, has been suggested as a member of the subfamily. [17] Young but already tall redwood trees (Sequoia sempervirens) in Oakland, California
The giant sequoia is usually found in a humid climate characterized by dry summers and snowy winters. Most giant sequoia groves are on granitic-based residual and alluvial soils. The elevation of the giant sequoia groves generally ranges from 1,400–2,000 m (4,600–6,600 ft) in the north, to 1,700–2,150 metres (5,580–7,050 ft) to the south.
The largest giant sequoia ever recorded, as well as potentially the largest tree which ever lived, was the Father of the Forest from Calaveras Grove. The exceedingly enormous tree collapsed centuries ago, and its still relatively well-preserved remains have turned into a popular tourist attraction.

Sequoiadendron giganteum, the giant redwood, is the largest tree in the world, and Sequoia sempervirens, the coastal redwood, is the tallest. [6] Ginkgo trees tolerate urban pollutants well, and are often planted in and near cities. [7] The pine family is the main source of softwood timber, paper pulp and turpentine. [8]
